On 8 June 1941, Allied forces commanded by British Lieutenant General Maitland Wilson that included the British Ninth Army, Australian, and Major General Paul Legentilhomme's Free French Forces, along with troops of the Transjordan Arab Legion, crossed from Palestine into Lebanon and Syria. By 15 June, they had reached the Syrian capital of Damascus, which fell on 21 June. On 13 July, Dentz and the Vichy French surrendered and the next day signed the Acre Convention. The fighting had claimed 4,500 Allied and 6,000 Vichy French casualties.
Syria was then turned over to the Free French authorities. The French recognized Syria's independence but continued to occupy the country, which was used as an Allied base for the rest of the war. Free French Commander General Georges Catroux became Syria's Delegate-General and Plenipotentiary. French authorities declared martial law, imposed strict press censorship, and arrested political subversives.
In July 1943, following pressure from Great Britain, France announced new elections. A nationalist government came to power that August, electing as president Syrian nationalist Shukri al-Quwwatti, one of the leaders of the 1925–1927 uprising against the French. France granted Syria independence on 1 January 1944, but the country remained under Anglo-French occupation for the remainder of the war. In January 1945, the Syrian government announced the formation of a national army, and in February it declared war on the Axis powers.
Syria became a charter member of United Nations in March 1945. In early May 1945, anti-French demonstrations erupted throughout Syria, whereon French forces bombarded Damascus, killing 400 Syrians. British forces then intervened. A United Nations resolution in February 1946 called on France to evacuate the country, and by 15 April, all French and British forces were off Syrian soil. Evacuation Day, 17 April, is still celebrated as a Syrian national holiday.
